INSTALLATION INSTRUCTIONS
Location
The pump should be located as close to the water as practicable and mounted on a firm base in
a well-drained position, high enough to prevent any flooding. It is the installer’s/owners
responsibility to locate the pump so that it can be accessed for service and maintenance. The
rear fan shroud should be installed at a minimum distance of 100 mm away from any walls or
obstructions. This is to allow adequate air flow from the fan to cool the motor. Overheating due
to a lack of cooling voids warranty.
WEATHER PROTECTION
It is recommended that the pump be protected from the weather.
Enclosures should be ventilated to allow a free flow of air for the fan cooled motor.
POWER CONNECTION
OASIS pool and spa pumps are suitable for connection to a nominal 240-volt 50Hz power supply.
The motor is equipped with a flex and 3-pin plug. If a power outlet is not available within 2 meters of
the pump, a 3-pin power point in a safe, dry place may need to be provided by an electrician.
Note:
•Pumps must be either
oSupplied by an isolating transformer, or
oSupplied through a residual current device (RCD) with a rated residual operating current
not exceeding 30mA.
•Extension cords are unsafe around pools and must be avoided.
•If the supply cord of this product is damaged the dealer or manufacturer must replace it,
with genuine OASIS pool and spa pump spares.
•Water temperature is not to exceed 45 degrees

PIPE CONNECTION
A barrel union is provided for connecting to the piping from the pool.
The pumps are designed to accept the following PVC Pipes:
•Inlet PVC Position 40mm pipe ID or 50mm fitting ID PVC pressure pipe fittings
•Outlet PVC Position 40mm pipe ID or 50mm fitting ID PVC pressure pipe fittings
The use of pipe with a smaller ID than those specified above is not recommended and may cause
damage to the pump voiding warranty.
A straight length of pipe measuring no less than 300mm should be installed in front of the inlet of
the pump allowing quieter and smoother operation.
Suction piping should be free from all air leaks and any humps and hollows, which may cause
suction difficulties.
The outlet piping from the pump should be connected to the inlet connection on the swimming pool
filter (at the filter valve).
For pump installations above water level, it generally requires a check valve in the suction line.
Do not use type ‘P’ (green) plumber’s glue on the barrel unions as this may cause damage to the
material used.
Always install pump for maintenance and service accessibility.

OPERATION
STARTING THE PUMP
To operate efficiently and to prevent damage to the pump there must be a free flow of water to
and from the pump. Before starting ensure that:
•All pipe work is correctly sealed.
•The pool/spa water level is at the correct height.
•That all appropriate valves are open and there is nothing preventing the flow of water
through the system.
1. First prime the pump by removing the strainer basket lid and filling the strainer basket area
with water. Replace the lid, ensuring that it seals on the large o-ring.
2. Connect to the power supply and switch on.
3. Allow the pump to run, so that any air trapped in the pipe work and pump may be expelled.
4. If prime is not established within approximately two minutes, as evidenced by a strong flow of
water from the outlet, switch off the pump for 10 secs and repeat the procedure. Continued
evidence of air under the hair and lint pot lid indicates an air leak in the suction piping work,
which should be rectified to avoid pump damage.
5. If water flow through the pump is continuously tedious to obtain at start-up after cleaning the
lint basket, then an examination of the system to establish a reason and correct the cause.
(ie. Check valve, air leaks, faulty seal/s, crack lid.
PUMP OPERATION
For optimum pump performance, the strainer basket housing should always be full of water and
free from air bubbles. The water level of the pool should always be maintained to at least
halfway up the skimmer box ensuring water is in the pump at all times. From time to time it
may be necessary to re-prime the pump. This should be carried out as described above.
LIMITS
Water temperature Max 45°C Ambient Temperature Max 55°C DBa @ 1 meter 62
WATER QUALITY
Maintaining balanced water chemistry is important to the life of your pool pump.
This pump is designed to be used with Pool & Spa water, balanced in accordance with Langlier
Saturation Index, with a pH level of between 7.2 and 7.8 and is regularly treated with a chlorine
sanitizing agent with the level not exceeding recommended chlorine levels.
Please consult your local pool shop regularly to have your water tested.

TROUBLE SHOOTING
If the pump does not operate, one of the following conditions may apply:
A. The power is not connected. For 240 volt only.
B. Check the power point by plugging in a portable appliance to ensure power is available.
C. Check fuses and the main power supply switch
D. Automatic overload is tripped. The pump has an in-built thermal overload, which will re-set
automatically after the motor has cooled following an overheating period. Determine the
cause of the overload tripping and rectify.
E. Pump needs to be disconnect for 10 secs and reconnected
F. Blockage is preventing the pump from rotating.
G. If plugged into chlorinator, disconnect and reconnect directly to power after 10 secs. If it
then works, please check your chlorinator manual.
H. Motor is burnt out - burning smell is evident. Replacement is required.
I. If you are unable to resolve any installation or operation difficulties with your OASIS pool
and spa pump, contact the supplier from whom the pump was purchased or you’re nearest
Authorized OASIS pool and spa pump Pool Equipment Service Centre. If any further
assistance is required, contact the OASIS Customer Service Centre at the address indicated
in this manual.
If the pump runs but there is no water flow or water flow is reduced, the following
condition may apply:
1. The filter requires backwashing or it is blocked.
2. The pump is not primed. (See Starting the pump)
3. There are air leaks in the suction piping. Check all piping and eliminate leaks, also check for
a loose strainer basket lid. Air bubbles in the water flowing back to the pool would indicate
a leak in the suction to the pump allowing air to infiltrate the pipe work.
4. The pump is not able to get water from the pool. Check that the valves to the pump are
fully open and that the pool water level is up to the skimmer box.
5. A leaking pump seal may also prevent operating. Evidence of this would be water on the
ground under the pump.
6. Blockage in the piping or pump. Remove the hair and lint pot strainer basket and check for
any blockage to the pump impeller entry.
7. To check it impeller is rotating, please lodge a flat-head screwdriver in the back motor
through the fan cowl and twist.
Removal of the Pump from Pipe work
To remove the pump, follow these instructions:
1. Switch off the power and remove the plug from the power source.
2. Close the water valves on the pool return and the pump inlet pipe work.
3. Remove the discharge & suction barrel unions taking care not to lose the o-rings.
4. Move the pipe work with the barrel unions attached until the pump can be moved clear.
